Determination of the number of turns and voltage of control winding of controllable reactor of transformer type

For the multi-objective optimization of controllable reactor of transformer type, the number of turns of control winding and control winding voltage must be got. So, the paper regards a new magnetic integrated structure of CRT as the research object and analyzes the equivalent circuit of a basic unit of structure. Each control winding current is taken as the integer times of the maximum of currents which are converted from control winding side to work winding side. According to the proportional relationship of current and voltage converted before and after, the number of turns of control winding and control winding voltage can be determined in the sequential single branch operation mode. Calculation results show that it is reasonable to take each control winding current as the integer times of the maximum of currents which are converted from control winding side to work winding side.
